ABSTRACT
The paper gives a summary of the life and work of Carl C:zon Caldenius who was a leading Quaternary geologist at the geological Survey of Argentina (Dirección de Minas, Geología e Hidrología) between 1925 and 1930. He made extensive mapping and geochronological work all over Patagonia, a work that, as far as the mapping is concerned, is still considered a masterpiece, correct into detail. At the same time as Caldenius a few other Swedish geologists were also employed at the Survey. Erik Ljungner is also briefly presented here. These scientists form a link between the 1901-1903 Nordenskjöld expedition to Antarctica and Patagonia and today’s Swedish-Argentinean cooperation in geology.
